INDUL linear diffusers enhance a feel-good climate inside the building

After around 50 years of intensive use since its inauguration in 1962, the plenary hall section of the State Parliament building was beginning to show signs of functional, structural and safety-related deficiencies. Some even gave rise to serious concern. Pragmatic solutions concerning spatial planning and layout were researched. After several years of intensive analysis, Blocher Partners from Stuttgart finally won the contract in 2013. A decision was ultimately made in favour of renovating the existing building.

The Blocher Partners' concept envisaged an intelligent combination of contemporary architecture and expert historic building preservation. The three-year refurbishment resulted in a new build constructed behind the renovated historic façade.

Respectful modernization combined with energy-efficient design

With its urban references and openness, the new plenary hall symbolises a transparent political system and the emergence of a futureproof building. Myriad glass frontages and spacious public galleries reflect the goal of architecturally representing a encouraging local residents to get involved and stay well informed.

With INDUL linear diffusers, which can be integrated into any desired ceiling design from just 15 mm due to their minimal slot width, a comfort climate was created in harmony with the architecture. Functional and ideal for modern working conditions.

Function linear diffuser INDUL

The supply air is divided into fine individual jets which distribute the supply air into the room at an angle of 45° alternately to the left and to the right. The result is an especially uniform air distribution with an optimal diffuse ambient air flow, and no noticeable draughts.

System advantages

  • Completely draught-free air distribution
  • Low diffuser widths, from 15 mm
  • Unobtrusive installation in ceiling joints
  • Temperature differences up to -14 K
  • Light, clean ceilings due to fine-jet characteristics
  • Simple, quick and clean installation in all ceiling systems
